Letters Patent No. 85,694, dated .Tamm/ry 5, 1869.

IMP/lROVEMENT IN SAW-BUCKLES AND FRAMES.

The Schedule referred to in these Lettera Patent and making part of the same.

To all whom 'it may con-cem l l Be it known that I, JOHN REILLY, of Baltimore city, county of Baltimore, in the State of Maryland, have invented acertain new and useful Improvement in Saw-Buckles for Saw-Frames, used in sawing stone, lumber, Spc.; and I do hereby declare the following to be -a full and exact description thereof, reference `being had to the accompanying drawings, -making apart of this 4specifcatiomin which like parts are indicated by like letters in theseveral figures.

The nature of 'my invention consists in a peculiar construction and operation of parts, to be here-after described, whereby one buckle will answer for a frame, which may hold a number of saws.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the drawingsy Figure 1 is a top view of. my invention, as applied to a horizontal saw-'ame;

Figure 2,'a central vertical section of same, ing a saw with teeth placed upward; whilst Figure 3 represents a similar section, the buckle turned up to be shifted to another saw-blade. A

A represents the saw-frame, which may contain vone or more blades, or a gang, asused both in stone and lumber-sawing.

It is well known, the blades require frequent stiiening ortightening, which is most generally done by wedges, and too frequently7 the driving in of one Wedge only loosens the others.

To remedy this is the object of my invention, whilst; my buckle or apparatus can bereadily applied to each blade in a frame, as well as to diierent saw-frames.

B represents thel sawfbla'de or blades, and,

a b, the stirrups at each end, passing through slots at the ends ofthe frame, whether horizontal or upright.

c is a wedge or key passing through a hole in the stirrup b, and nearer the end of b is another pin-hole,

1,'for a pin,A e, to passthrough, connecting it with'the show--v buckle C, by means of pin e,

-is to screw up a screw-bolt, D, passing through it, and which is made so as not to turn in its socket or hole through O, and which has holes fthrough its bifurcated front end, for the pin e to pass through, thus connecting the frame, the saw, and the buckle.

The buckle C has two or four bearing-points, g, to rest against the frame A, and two lugs, h, with holes through them, so as to slide C along a rod, I), which rests in or upon suitable bearings E, which will be varied somewhat to suit a vertical or horizontal frame.

F is a crank or handle, screwing upon the bolt D.

The operation -is as follows:

To tightenthe saw-blade B, the parts all being connected as shown in figs. l and 2, all that is necessary vthe handle F, 'when the tapering wedge or; key drops further into its opening lstig' rup b.

To tighten, say, an adjoining blade, take out the turn up the buckle, as shown in g. 3, so as to clear the end of b, slide it to one side, and attach it to the next or other blade requiring tightening, and repeat the operation.` y

b and D may have hooked ends to grapple each other, or they may be connected i any v.desirable Way.

By means of hooks, instead of the lugs h, the buckle may be more readily attached to or detached from rOd D, and the rod and buckle can both be removed from bearings on frame A, and be transferred to similar ones on other frames, thus making one buckle answer for any desired number of frames.

Having thus described my invention.,

What I claim as new, and desire to secure by Letters Patent of the United States,l is The buckle C, constructed and operated in the manner substantially as shown and described, and for the purpose set forth.

` JOHNA REILLY.
